I specialize in LLM solutions like RAG chatbots, agent workflows, summarization, classification/triage, and text-to-code tooling, with a strong focus on reliability, latency, cost control, and safety guardrails. On the engineering side, I develop backend services with Python (FastAPI/Flask), Node.js/TypeScript, Go, and Java, and ship clean, responsive frontends with React/Next.js and Angular. I’m comfortable with data pipelines and analytics (SQL + large datasets), integrating third-party APIs (OAuth/JWT, webhooks, REST/GraphQL), and deploying on AWS/Azure with Docker/Kubernetes and CI/CD. I’ve worked on healthcare, procurement intelligence, and fintech systems where security, auditability, and real-world performance matter. I enjoy owning features end-to-end, collaborating closely with product/stakeholders, and shipping fast without sacrificing code quality. less -

My strongest work is practical reliability engineering: stabilizing systems, cleaning up messy environments, automating repeatable operations, and leaving behind clear documentation so the next person can maintain the setup. I specialize in Linux server administration, production troubleshooting, operating system migrations, infrastructure automation, monitoring, storage work, virtualization, web hosting recovery, and cloud/VPS operations. I work with RHEL, AlmaLinux, SLES, Ubuntu, HP-UX, Solaris, AIX, Azure, AWS, IONOS, Hetzner, Hostinger, DigitalOcean, cPanel/WHM, Plesk, WHMCS, Docker, Kubernetes, KVM, Libvirt, Proxmox, VMware, MySQL, MariaDB, PostgreSQL, and DB2.

I also work with practical AI infrastructure and local/self-hosted model tooling. My AI-related work includes Ollama, Open WebUI, LiteLLM, vLLM, SGLang, llama.cpp, SurfSense, JupyterLab, Caddy, Nginx, remote GPU hosts, OpenAI-compatible gateways, SSH tunnels to remote model servers, local model workflows, token-usage monitoring, AI gateway routing, coding-agent integration, Qwen/Ollama behavior control, prompt harness design, debug visibility, and compliance/retry loops. My work style is direct, practical, and evidence-based. I clarify the goal, inspect the environment, identify risks, build or fix in focused steps, test in realistic conditions when possible, deploy carefully, validate the result, and document the handoff path. I communicate clearly, prefer reliability over hype, and am fluent in English and Spanish. I am a strong fit for Freelancer.com projects involving Linux reliability, migrations, server recovery, hosting-provider infrastructure, Ansible/Bash automation, production troubleshooting, monitoring cleanup, self-hosted AI infrastructure, local model tooling, and practical workflow automation. less
